1. Description

The friction measuring apparatus is used to

measure static and rolling friction between dif-

ferent kinds of surfaces.

A friction track in the form of a mounted, rotating

U-shaped structure made of aluminium serves as

the basis for the experiments. Between the fric-

tion bodies and the friction plane, there is a long,

inlaid friction surface made of plastic, which can

be pulled at a uniform velocity. At the opposite

end, a dynamometer is horizontally clamped to

the friction track. The dynamometer shows the

frictional forces between the surfaces, resulting

from the movement of the sliding friction surface.

When the friction surface begins to move, the

body resting upon it experiences static friction

and is dragged along with the sliding surface. As

the sliding friction surface continues to be moved

at uniform velocity, the static friction changes to

sliding friction and the friction body remains at a

state of rest relative to the friction plane.

The friction bodies have surfaces of different

areas and degrees of roughness. This makes it

possible to investigate the influence the area of

contact and the nature of the surface has on the

frictional forces.

It is possible to vary the angle of the friction

track, thereby creating an incline to the horizon-

tal plane. In this way, the normal force with

which the friction body acts upon the particular

surface can be made to vary.
